Quick Update R&S NGB 32/10:
Seller agreed to refund me the 50 Euro I've asked for.
I'm aware, that if that had happened over ebay, things would have been better going for me, but I'm satisfied.
I'm glad, that this could be handled in a civilized way.
But before I can take care of this PSU I have to look after a RF remote control from a friend of mine.
Intermittend failure. One second it is working, the next second not.
I'm suspecting the receiver, because when I looked at the transmitter, all was well.
Oh dear ....
